Trait defining storage operations for vectors.

Required Methods

fn store(&mut self, id: u64, vector: &[f32]) -> Result<()>

Stores a vector with the given ID.

Errors

Returns an error if the write operation fails.

fn store_batch(&mut self, vectors: &[(u64, &[f32])]) -> Result<usize>

Stores multiple vectors in a single batch operation.

This is optimized for bulk imports:

• Single WAL write for the entire batch
• Contiguous memory writes
• Single fsync at the end

Errors

Returns an error if the write operation fails.

fn retrieve(&self, id: u64) -> Result<Option<Vec<f32>>>

Retrieves a vector by ID.

Errors

Returns an error if the read operation fails.

fn delete(&mut self, id: u64) -> Result<()>

Deletes a vector by ID.

Errors

Returns an error if the delete operation fails.

fn flush(&mut self) -> Result<()>

Flushes pending writes to disk.

Errors

Returns an error if the flush operation fails.

fn len(&self) -> usize

Returns the number of vectors stored.

fn ids(&self) -> Vec<u64>

Returns all stored IDs.

Provided Methods

fn is_empty(&self) -> bool

Returns true if the storage is empty.
